SPECIFICATION forming part' of Letters Patent No. 302,606, dated July 29, 1 884.

To aZl whom it may concern.-

Be it known that I, PATRICK VVARD, a citizen of the United States, residing at Seneca Falls, in the county of Seneca and State of New York, have invented a new and useful Tar-Burner, of which the following is a specification, reference being had to the accompanying drawings.

Figure 1 is a front elevation of the apparatus applied to a furnace. Fig. 2 is a detail view of the casting which surroundsthe tarburner, and Fig. 3 is a vertical longitudinal section through burner and its surrounding casting.

This invention has relation to tar-burners for gas-houses; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims appended.

Referring by letter to the accompanying drawings, A designates the brick-work that supports the casting A, which surrounds the tar-burner B, which consists of a two-inch pipe supported within the casting A by spokes or radial arms B, connected to the pipe B and the casting A at their ends, to form an airpassage all around the tar-burner, which keeps it cool. The tar-burner is provided with a plunger, 0, consisting of a disk, 0, supported by three inclined rods, D, connected at their rear ends to a small disk or other connection, D. The front end of the burner B is closed by a screw-cap, H, provided with a stuffingboX, I, through which the handle K of the plunger passes. A set-screw, L, in the casting prevents the burnerfrom leaving its place in the casting. The tank which supplies the steam and tar receiver M holds three barrels of tar, and is connected by a pipe, N, provided with a stop-cock, O, to the vertical steampipe P, having a stop-cock, O, and a condensed-water outlet, 0 immediately above it, both the stop-cock O and the water-outlet cock 0 being above the connecting points of the pipes N and I. The pipe 1? leads into the steam and tar receiver M. A horizontal tar-pipe, Q, is connected by a T- joint with a vertical tar-pipe, Q, and is provided with a stop-cock, R, between this joint and the steam plies the air to the tar-burner. is admitted to the steam and tar receiver warms and thins the tar, so that it will run to the tarburner under a light pressure of steam, which comes upon it from the steamgenerator. The burning tar creates a suction from the air-chamher, that causes the air and tar, under the steampressure, to be forced into the fire together and be thrown the entire length of the fireplace. By this constructionI save all the coke that is necessary for heating the retorts, and at the same time preserve the fire-arch and retorts by preventing the steam from entering the fire With the tar. If the tar were permitted to enter the fire without mingling with the air, it would bake in a hard lump at the end of the burner, whereas by introducing the tar and air together under a light steam-press ure it will be thrown the whole length of the fire-place.

To clean the tar-burner the plunger should be pushed in. The draft around the burner keeps it cool and furnishes the draft for the fire.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. The herein-described method of introducing tar and air to a tar-burning furnace, consisting in forcing the tar to the burner from a steam and tar receiver by light pressure of steam upon the tar, and admitting air to the tarpipe before it reaches the tar-burner, so that the tar and air will both enter the fire together, substantially as specified.

2. In a tar-burner, the combination, with the burnerB, 0f theplunger consisting of the disk G, supported by three inclined rods connected to the smaller disk I), and the handle K, passed through the stuffingbox I, substantially as specified. 1

3. The combination of the steam and tar receiver, the tar-burner within the open casting, the air-chamber, and the tar and air pipes, constructed and operating substantially as specified. v

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

Ill. PATRICK 2 WARD.
